UDP Relay
This menu configures the Total Access 600 to act as a UDP relay agent for applications requiring a
response from UDP hosts that are not on the same network segment as their clients.
Mode
When this option is set to ON, the Total Access 600 will act as a relay agent.
UDP Relay List
Up to four relay destination servers can be specified in this list.
Bridge
The BRIDGE menu is used to set up the bridge parameters for the Total Access 600. The bridging function
runs at the Media Access Control (MAC) level which allows any protocol packets that run over Ethernet to
be forwarded. Bridging can run concurrently with IP. However, when IP routing is active, IP packets (which
include ARP packets) are not bridged.
Mode
This is used to enable the bridge function.
Address Table
The Total Access 600 automatically maintains a table of MAC addresses detected and associates those
addresses with the LAN or WAN port from which they were received.
RELAY ADDRESS
This is the IP address of the server that will
receive the relay packet.
UDP PORT TYPE
STANDARD (def)
The following standard UDP protocols are
relayed when set: DHCP, TFTP, DNS, NTP
(Network Time Protocol, port 123, NBNS
(NetBios Name Server, port 137), NBDG
(NetBIOS Datagram, port 138), and BootP.
SPECIFIED
When set, the UDP port (1 to 65535) can be
specified in the UDP Port columns (up to
three per server).
UDP PORT 1, 2, 3
Used for specifying UDP ports to be
relayed. These fields only apply when
UDP
PORT TYPE is set to SPECIFIED.
AGING
The maximum time an idle MAC address
remains in the table before being removed. The
value is in minutes.
FORWARD POLICY
When this parameter is set to UNKNOWN (def),
any bridge packet with a destination MAC
address that is not in the bridge table is
forwarded to all other ports. When set to
K
NOWN, the packet with the unknown
destination MAC address is dropped and is not
forwarded.
